Description
The TPS54320 is a full-featured 17-V, 3-A
synchronous step-down converter which is optimized
for small designs through high efficiency and
integrated high-side and low-side MOSFETs. Further
space savings are achieved through current mode
control, which reduces component count, and by
selecting a high switching frequency, reducing
footprint of the inductor.
The output voltage start-up ramp is controlled by the
SS/TR pin which allows operation as either a stand
alone power supply or in tracking situations. Power
sequencing is also possible by correctly configuring
the enable and the open drain power good pins.
Cycle by cycle current limiting on the high-side FET
protects the device in overload situations and is
enhanced by a low-side sourcing current limit which
prevents current runaway. Hiccup protection is
triggered if the overcurrent condition has persisted for
longer than the preset time. Thermal shutdown
disables the part when die temperature exceeds
thermal shutdown temperature. The TPS54320 is
available in a 14-pin, 3.5-mm × 3.5-mm VQFN,
thermally enhanced package.
